Title: Linear motor
Inventor: OTAKE YUTAKA
IPC: H02K7/06
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To eliminate necessity for providing a stopper mechanism or the like on the outside and facilitate handling, by suppressing movement in an axial direction of a screw shaft by contact of a protruded part end face of a slide member formed in a central part of the screw shaft with an end face of a bearing, so that rotation of a rotor can be stopped. SOLUTION: A slide member 11 is formed in almost a central part of a screw shaft 13, also a plurality of protruded part end faces are formed in both ends in an axial direction of this slide member 11. When these protruded part end faces and an end face 61b of a fixed nut 61 or an end face 63b of a bearing 63 concurrently having a function as a bearing are brought into contact, sliding in an axial direction of the screw shaft 13 is suppressed to stop rotation of a rotor 15. In this way, this device can be used without providing a stopper mechanism regulating a moving amount in an axial direction of the screw shaft 13 in the outside or a sensor mechanism or the like regulating a rotational amount of the rotor 15.

Title: Overload protecting device for multioutput switching power source
Inventor: NISHIO TAKEICHI
IPC: H02M3/28
Filed: 1981-09-24
Abstract: PURPOSE:To protect a small output circuit element against an overload by limiting the collector current of a switching transistor (TR) when some output becomes an overload, and stopping switching operation and performing resetting through a timer. CONSTITUTION:An overcurrent detecting resistance 17 detects the collector current of a switching TR18 in every cycle of switching and when the current exceeds a limit level, the TR18 is turned off to limit the collector current. At the same time, a driving control circuit 19 outputs a start signal (to hold the output of a terminal OCL at a high level), and a TR33 for resetting release turns on after the time determined by a resistance 30 and a capacitor 31 to release a multivibrator 29 from being reset, thereby starting astable operation. Consequently, an output TR27 turns on and off to turn on and off a control circuit 19 for driving. When an overload state is reset, the multivibrator 29 is reset and the power source output recovers.

Title: Printing head
Inventor: AOKI KENICHI
IPC: B41J2/275
Filed: 1987-06-17
Abstract: PURPOSE:To achieve stabilization of action and improvement of high speed follow-up property by restraining rebound since kinetic energy in returning of an armature is effectively absorbed, by using an injection molded plastic magnet as a stopper component of the armature. CONSTITUTION:A stopper component 6 of an armature is formed by an injection molded plastic magnet and is fixed to a rear plate 15 via a rubber state elastic component 16. Kinetic energy in returning of an armature is effectively absorbed by combination of attraction keeping force of the plastic magnet forming the stopper component 6 and the elastic component 16, and the armature can be quickly made to stand still on the stopper component by restraining generation of a rebound. Magnetic force of the stopper component 6 is determined to an extent that the armature quickly rises to act by attraction force acting on the armature in coil communication of an actuator and rebound of the armature is restrained in returning of the armature.

Title: Water pressure regulator
Inventor: FUJISAKI OSAMU
IPC: F23N1/08
Filed: 1978-12-08
Abstract: PURPOSE: To positively start and stop a ventilating fan, by operating a reed switch in response to a relief valve.  
     CONSTITUTION: When water is let pass through a water supply passage 1, an opening-and-closing valve 14 is opened through a functioning lever 15 because a diaphragm 8 is subject to water pressure and left moved, thus fuel is fed to a combus- tor 5 and burnt. Meanwhile, a rod 16 is left locomoted by means of a spring 17 because a relief valve 11 is also shifted left against the force of a spring 13 with the left movement of the diaphragm 8, thus a lead switch 19 reaches a closing region. That is, a ventilating fan is started becasue the lead switch 19 is closed. Since the rod 16 keeps distance l 4 , which does not damage a control condition of the relief valve 11, under this condition and parts from the relief valve 11, there is no danger that the relief valve 11 gives force causing trouble for controlling water supply pressure. Since a pressure receiving diameter of the rod 16 is small, force for open- ing the lead switch 19 can sufficiently be opposed by means of the spring 13 by the water supply pressure.
